Answers
Step-by-step explanation:
heya here is your answer.........
1 CASE
LET POINTS OF SCHOOL Y BE a
then points of School X will be 8+a
2 Case
Points of school Y be a
then school X is 3a
since overall points in case 1 will be equal to case 2 therefore
8+a+a=3a+a
8+2a=4a
8=2a
a=4..
8+a=12...
so school X have 12 points and school Y have 4 points
The points of school X is 12 points
The points of school Y is 4 points
Step-by-step explanation:
school X and School Y play each other in a competition.
School X has eight more points than School Y
i.e
X = 8+Y ..(1)
school X has three times as many points as School Y
i.e
X = 3Y ..(2)
substitute the equation 2 in 1
then we get
3Y = 8+Y
3Y-Y = 8
2Y = 8
Y = 4
now , put the value of Y in equation 2 we get ,
X = 3Y
X = 3× 4 = 12
hence ,
The points of school X is 12 points
The points of school Y is 4 points
